Problem 54P
A boundary layer is a thin region (usually along a wall) in which viscous forces are significant and within which the flow is rotational. Consider a boundary layer growing along a thin flat plate (Fig. P7-57). The flow is steady. The boundary layer thickness δ at any downstream distance x is a function of x, free-stream velocity V∞ and fluid properties ρ (density) and μ (viscosity). Use the method of repeating variables to generate a dimensionless relationship for δ as a (function of the other parameters. Show all your work.
